Missing from the article is rav1e, which encodes AV1, and hence AVIF, a lot faster than the reference implementation aom. I've had cases where aom would not finish converting an image in a minute of waiting what rav1e would do in less than 10 seconds.
- JyrkiAlakuijala 3y agoIs rav1e pareto-curve ahead of libaom pareto-curve? Does fast rav1e look better than jpegli at high encode speeds?
- btdmaster 3y agoDifficult to know without reproduction steps from the article, but I would think it behaves better than libaom for the same quality setting. Edit: found https://github.com/xiph/rav1e/issues/2759 https://github.com/xiph/rav1e/issues/2759
- JyrkiAlakuijala 3y agoIf Rav1e found better ways of encoding, why would the aom folks copy it in libaom?
- pornel 3y agorav1e is generally head to head with libaom on static images, and which one wins on the speed/quality/size frontier depends a lot on the image and settings, as much as +/- 20%. I suspect rav1e has an inefficient block size selection algorithm, so the particular shape of blocks is a make or break for it. I’ve only compared rav1e to mozjpeg and libwebp, and at fastest speeds it’s only barely ahead.
- jonsneyers 3y agoBoth rav1e and libaom have a speed setting. At similar speeds, I have not observed huge differences in compression performance between the two.
